. AUTOMATIC T312 MECHANISM FOR END-MATCHING MACHINES.

To all whomit may concern Be it known that I, WALTER TAYLOR, a subject of the Kingdom of Great Britain, residing at Nashville, in the county of Davidson and State of Tennessee, have invented certain new and useful Improve- ,ments in Automatic Trip Mechanism for End-Matching Machines; and I do hereby declarethe following to be a full, clear, and

exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use, the same.

This invention relates to automatic trip mechanism for end matching machines, and

in particular to automatic regulating at- The principal object of this invention is 1 to provide an arrangement to stop the operation of an end matching machine upon receiving material of an undesirable thickness. 7

One of'the objects of this invention is to provide automatic means which controls trip mechanismt'o release the drivingmechanism of an end matching machine.

Another object of this invention is to pro- -vide an. arrangement whereby automatic trip mechanism can be adjustably regulated to receive material of an undesirable thickness.

A still further object of this invention is ,to provide a flexible arrangement to automatically trip and release the driving mechanism upon the receiving of material of an v undesirable thickness.

A. still further object of this invention is to provide an arrangement adapted to stop [an end matching machine when material is received 1nto the machlne 1n a wrongful position. I

Other objects and advantages of this invention will be hereinafter more clearly set forth in the specification and pointed out in the claims. 45

thereto. A belt operated pulley 6 operated by means of a belt is'mounted upon a shaft 8, said shaft being mounted through each of the standards 2, 3 and 4. Suitably mounted from the base 1 is positioned a.

driving shaft 100-and mounted upon the dr ving shaft 100 is a pulley 101. around WhlCl'l extends a belt 9, said belt passing over an idle pulley 104 and around a pulley carried by a shaft 10, said shafting having a circular saw 11 mounted thereon adapted to be rotated in a vertical plane and sever the end of each piece of material as it passes through the machine. A second pulley 102 i is mounted upon the driving shaftlOO upon which operates a belt 12' likewise running over an idle pulley103 in such. manner as to give a quarter twist to the belt 12 to operate .a vertically rotative shaft 15 which is suitably mounted by means of bearings 16 and ,17,and which carries at the top thereof a circular saw 18 adapted to be rotated in a 7 horizontal plane, and groove the end of each piece of material.

Between the proj noted, is rotatively mounted a shafting 23 which carries suitable sprocket wheels 24. A second shafting, 25, in the same horizontal 'plane with the shafting 23, is mounted between the standards 2 and 4 at the rear end thereof, and likewise carries suitable sprocket wheels similar to the sprocket wheels 24. Endless chains 26 are extending around the sprocket wheels, these chains having projecting dogs 27 thereon adapted to. feed material to the device. A suitable driving gear 105 is mounted upon the shafting 25 and is driven by means of a sprocket chain29 operating oversprocket 106 mounted on shafting109, as plainly shown in Fig.

the springs 30. The top portions of the 7 members .38 are suitably recessed as at 3 1 to receive the transversesupporting member ections 5, previously.

35 which is suitably fastened as at 36 to the erably formed of spring steel. which press the material upward as it is passed through the machine by the conveyer 26the material being pushed through by means of the dogs 27 previously noted. Above these members 37 are bars 38 to which are pivotally mounted gage members 39, said gage members being pivotally mounted at 40. g

A spring actuated link member 41 is pivoted as at 42 in the member 39, the upper end of which is suitably mounted through a bearing sleeve 42 in such manner as to allow it to contact with the bell crank lever 43, this bell crank lever being pivoted at 44 to the standards. The connection link 45 is pivotally connected to the upper end of the bell crank lever 43 at one end thereof and pivotally connected as at 146 at the opposite end to a lever arm 47, which is rigidly mounted upon a shafting 48 rotatively mounted through each of the top portions of the standards 2, 3 and 4. The opposite end of the shafting 48 has rigidly mounted thereon a locking pawl 49 which is adapted to be caught under the hooked upper end of the link rod 50 suitably mounted through bushings 51 and 52 on the standard 2. A second rod 53 is connected by means of a turn buckle 54 to the member 50, which is pivotally connected as at 55 to a pivoted pulley support 56 the rear end of which is pivotally mounted as at 57 in the support 58 projecting from the base 1. The opposite end of the member 56 carries an idle pulley 59 engaging the driving belt 7.

In operation this device is set at the desired adjustment, the end matching machine started in operation and material fed to the conveyer chain 26 each one of the projecting dogs 27 carrying it through tlie machine and over the members 37, previouslynoted, the members 30 pressing the material up into position. If the material should be greater than the desired thickness, or improperly positioned in the machine, it lifts the pivoted member 39, thereby raising the member 41, which in turn actuates the bell crank lever 43 pushing rearwardly against the connecting link 45 to turn the lever arm 47. This actuates the shafting 48 to turn the locking pawl 49 thereby releasing the hook link rod 50 allowing said link rod to drop through the medium of gravity to release the lever 56 and consequently the idle pulley 59 from engagement with the driving belt 7 thereby loosening said driving belt so that the end matching machine is stopped from operating. The undesired or misplaced materialis then removed from the machine, and the link 50 re-hooked with the pawl 49 which tightens the driving belt, thereby causing the machine to resume operation.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. An automatic trip mechanism for end matching machines, comprising a spring pressed pivoted gaging means, a plurality of spring pressed supporting devices adapted to successively force objects against said gaging means, a trip mechanism operated by said gaging means, an idle pulley a driving belt and pivotally mounted means carrying said idle pulley and connected to said trip mechanism to engage the idle pulley with or release the same from the driving belt of said end matching machine.

2. An automatic trip mechanism for end matching machines, comprising; a plurality of resiliently mounted supporting devices, pivotally mounted gage members above said supporting devices, a resilient mounted member pivotally connected to said gage member and operated thereby, a bell crank lever operated by said last mentioned means, a connecting link pivotally connected with said bell crank lever, trip mechanism connected to said link to operate thereby, a driving belt and an idle pulley connected to said trip mechanism and engaging the driving belt of said end matchingmachine to be released upon the operation of said trip mechanism when actuated by said first mentioned gage member.

3. An automatic trip mechanism for end matching machines comprising; a base, a plurality of standards therefrom, a plurality of vertically mounted supporting members mounted in a portion of said standards, spring means supporting said members in an upward position, a platform supported by said vertically mounted means, and adapted to receive the ends of material, gage members pivotally mounted above said last mentioned means, means actuated by said gage members, bell crank mechanism actuated by said last mentioned means, trip mechanism, a link rod connecting said bell crank lever to said trip mechanism, a driving belt and means connected to said trip mechanism and engaging the drive belt of said end matching machine to be released from the belt upon the operationof said pivoted device.

' 4. An automatic trip mechanism for end matching machines, comprising the combination with standards, means to carry material over the standards and additional means to direct upward pressure on said material, of pivotally mounted gage members immediately above the path of the masaid link members, springs surrounding sald hnk members between the bearlngand gage members, driving means for the machine and an automatic trip mechanism cooperating with said link members and the driving means of the machine'to stop the motion of the machine when undue pressure of material is directed upwardly against said gage members.

5. An automatic trip mechanism for end matching machines, comprising standards, a plurality of spring pressed supporting bolts vertically movable in said standards, springs adapted to direct upward pressure on the bolts, yielding platforms over the upper ends of the bolts, means to convey ing means of the machine to stop the operation of the machine When undue pressure of the material is directed against the gage 1 member.
